Is there a cost-efficient way to store or dry grass clippings?
It depends how valuable the clippings are to you. If you are saving them to feed a horse in winter, then you have to balance the cost of drying them against the cost of buying hay later on. The sun is the most cost-effective way of drying grass. This is how farmers have made hay for hundreds of years. * Cut the grass and leave it to dry in the fields. * Turn the drying grass from time to time so that it all dries evenly. * Gather the grass and store it (in haystacks or barns) so that it stays dry till it is needed. The cost of using fossil fuel to run a drying machine would seem to put it into the too-expensive haybasket.
